A crate of eggs is located in the middle of the flatbed of a pickup truck as the truck negotiates a curve in the flat road. The

oksian1 [2.3K]

Answer:

v = 14.35 m/s

Explanation:

As we know that crate is placed on rough bed

so here when pickup will take a turn around a circle then in that case the friction force on the crate will provide the necessary centripetal force on the crate

So here we have

$\mu mg = \frac{mv^2}{R}$

here we have

$\mu g = \frac{v^2}{R}$

now we know that

$v = \sqrt{\mu Rg}$

here we have

$\mu = 0.600$

R = 35 m

g = 9.81 m/s/s

now plug in all values in above equation

$v = \sqrt{(0.600)(35)(9.81)}$

$v = 14.35 m/s$

Using the rules for significant figures, what do you get when you multiply 67.6 by 1.2?

Paul [167]

Answer:

B. 81

Explanation:

When you multiply two numbers, round the answer to the least number of significant figures available. 67.6 has three significant figures, and 1.2 has two significant figures. So we round to two significant figures.

If the amplitude of a sound wave is tripled, by what factor will the intensity increase?

Shtirlitz [24]

Answer:

By a factor 9

Explanation:

The intensity of a sound wave is proportional to the square of the amplitude of the wave:

$I \propto A^2$

where

I is the intensity

A is the amplitude of the wave

In this problem, the amplitude of the sound wave is increased by a factor 3:

A' = 3A

So the intensity would change by

$I' \propto A'^2 = (3A)^2 = 9 A^2 = 9I$

So, the intensity would increase by a factor 9.
